Yes, I too, have found Mike Mixon's video tutorials to be very informative, especially for a beginner(like me). I also bought one of his book bundles(#3) and get his registrations(for the songs in that bundle) emailed to me when he does a video. From there I take some of his ideas and expand on then, to fit my preferences.
For instance, he likes to put each song in one registration bank with 10 songs in all, in one bank. I prefer to put each song in it's own bank, using the registration buttons for the voices rather than the OTS buttons for voices like he does. For me, it gives more possibilities but this is just my preference(and not meant as a criticism of his way, just different ways of doing things)
But Mike really does use so many of the features in his tutorials of the Genos, I have learned a lot from them. And as mentioned, after he does a video, he will email you with the reg and the pdf file with all his fingering and settings for that song, he used(if you have bought a book bundle from him).
(Originally I looked into buying the Genos from him because he has some interesting packages put together, but, since I do not live in the U.S., the customs would have made it too expensive.)
